I very much like the plain ES5 solution by @lexlohr . Here's another, more generic version that lets you rotate an array by a variable number of positions:
const rotateArray = (array, count) => { const arr = [...array]; count = (count || 0) % arr.length; if (count < 0) count += arr.length; var removed = arr.splice(0, count); arr.push.apply(arr, removed); return arr; }
